I WATER-GAS- AP PARATus.

To (all w iz/0112 it may concern: i

Be it known that 1, JOHN RUsBY, a citizen of the United States, residing at-Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain s new and useful Improvements in Water-Gas F Apparatus, of which the following is a speciiication.

The principal object of the present inven tion is to provide means for definitely controlling the quantity and quality of the product'ion of gas. By these means the attendant is enabled to introduce a definite volume of air during the intervals of each blow regardlessof fire and other conditions in the generating apparatus, so that during the successive runs or gas producing periods, the

apparatus will be in any definitely desired condition of heat andthus the introduction of oil and steam or the gas making process, as a whole, is effected under such conditions that the various steps in the gas making process which are productive of the best results may be accomplished and the apparatus worked most. economically and efficiently.

To these and other ends hereinafter set .forth ,the invention comprises the improve- .n'icnts to be 'presently described' and ,finally claimed. In the drawings, Figure 1, 1s a top or plan 2, a carbureter, 3, a .superheater, and 4, the seal' .of the eduction' end of-the apparatus Theseare the ordinary and 'Well understood parts of a water gas apparatus and they are appropriately interconnected and provided- -With oil andsteam connections which are too wellunderstood to require description or v illustration. I

I 5, is an air-pipe from'whichair is conducted to the variousparts of the apparatus by' means of branch pipes 6, 7-,and8: There are- 10, 1s ana utage, sometinies designateda Vnturifltube, and it is interposed in the pi es or branches through which air is supplled to the parts'of the apparatus. This ajutage afi'ords means for indicatingl thevol unie of air-p'er second or other unit of time passing through it by reason of the'diflerent Specification of Letters Patent. I

respectively, its most contracted area -0'I throat; andiits' larger area on each side of the 9 throat and since this indication is continuous,

it. enables the attendant at a glance to knowv the yolume of air passing tojthe apparatus.

In order to operate water gas -"apparatus I most economically and efliciently, it is do-- sir a ble to perform each of the stepsiof the pro'cess-in. the manner that has beerfa'scer tainedto bemosteflicientl For instance,at-'- each blow a predetermined volume of air I;

should be introduced, otherwise-the app'ara' tus' will not be properly heated for the reception of a predetermined quantity of. oil andsteam; the volume of air passing through lt'under a given pressure, in some cases -perm'1tt ng too-- The condition f. the fire will effect' I large-a volume of air to pass with the result that fuel is unnecessarily consumed and the' apparatus-fprobably' too highly heated, and in other cases, recluding the passage ofjsufficient air in w ich case the requisite heat is plan, The volume: of gas made is substantiallylpropo rtional' to the quantity of air in-" steam and oil'a're supplied. Fromthe foregoing the importance of the admission of a pie-determined volume'of air 1s"a'p arent.

11, is a pressure gage, shown as of t ewell not attained for carrying out the gas making process in accordance with the pre-arranged 1 -tr'oduced'provided .the proper quantity of d form provided with pet' cpcks ,12, and with valves. .13, andit is a 1 1-" ranged Where the attendant canaeadily see 1t; For example, these various pressure gages arearranged above the operatmgfloor v 15, is a scale'by which thejgages canbe 'read and it may be arranged so as to be slidabl'yjmounted in order toadjust its position in 95 respect to the fluid leveliin the U-shaped gage; Th arms'of the'gage-are connected In operating the appa the attendant knows in adirance the volumeof air thatis to be introduced andhe can at by tubes or pipes 16 and 1 7 appropriate tiisiiiiiin gtheblowp all times accomplish this byreference tothe Y pressure gages; If they indicate that too much or too little air is passing to the a pas ratus, the attendant accordingly regu ates the supply'of air by the valves 9. In/this way the pre-determined volume of air is intro]- duced regardless of'fire and other conditions.

so that the next steps ofthe-gasmaking process may be carried on in a pre-"determmed manner; thus the operation, as a Whole, may

be carried on in that manner which is known 'to be the best instead of being carried on dition of the fire and other conditions will materially change the volume of air intro duced. The introduction of different volumes of air produces different results and in consequence if the later steps of the process are carried on according to pre-determined rule they will not be uniformly effective and, economical.

tity and quality of the production'of gas,

which means comprise the gas generating ap-- paratus' and its regulatableair supply connections and an ajutage interposed in said connections and provided with a pressure gage, whereby 'the attendant is enabled to in troduce a definite volume of air during the interval of each blow regardless of fire and other conditions inthe apparatus, substantially as described.

In" testimony whereof I have hereunto i signed my name f JOHN M, RUSBY.
